Customize your social images with the Social Image Generator

The Social Image Generator (SIG) helps you automatically create a unique image for each post before sharing it to your connected social accounts. This guide will show you how to enable the feature, customize your image, and use default settings to streamline your workflow.

This feature is only available with a paid Jetpack Social plan.

Enable the Social Image Generator feature

To turn on the Social Image Generator:

1. Log in to WP Admin → Jetpack → Social.
2. Toggle on Automatically share your posts to social networks.
3. Switch on Enable Social Image Generator.

When enabled, SIG will be active by default for new posts. If it’s turned off, you can still activate it manually in the post editor.

The Social Image Generator works only with the Block Editor. It is not compatible with the Classic Editor or plugins that rely on it, such as WooCommerce.

Customize your social image in the post editor

Once enabled, you can preview and customize your image directly in the editor:

1. In the Block Editor, click the Jetpack icon (or Social icon) in the top-right corner to open the Social panel.
2. Scroll to the Share to Social Media section.
3. The “Link Preview Image” option, with the “Enable Social Image” toggle, is the feature to work on.
4. Customize the following options by clicking on the Settings link:
   • Preview: See a live preview of your social image.
   • Image Type:
     • Featured Image – Uses your post’s featured image.
     • Custom Image – Upload your own image.
     • Plugin Default Image – Uses the default image set by your site admin.
     • No Image – Displays only your post title or custom header.
   • Custom Header: Add your own text to appear on the image. By default, this uses the post title.
   • Fonts: Add the option of choosing a preferred font to match with the blog and post layout.
   • Templates: Choose from a selection of predesigned layouts.
5. Click Save when you’re done.

Automatic Social Preview Images

As of Jetpack v15.0, the Social Image Generator can now create a social-preview image for you automatically. If you don’t choose or customize an image before publishing or sharing your post, Jetpack will generate a default preview image based on your post’s title and your active design settings.

You can still manually replace or edit this image at any time, but you no longer need to select one before sharing: Jetpack will take care of it for you.

Set a default image for new posts

Site admins can configure a default image for social shares. This image is used when no featured or custom image is selected in the post.

To set a default image:

1. In WP Admin → Jetpack → Social, click Change defaults under Enable Social Image Generator.
2. Under Default Image, click to upload or select an image from the Media Library.
3. Click Save.

Choose fonts for your social images

When customizing your social images, Jetpack Social Image Generator lets you select from a range of clean, legible fonts designed to look great across platforms like X (Twitter), Facebook, and LinkedIn.

From the same screen, you can also choose a font style that best matches your site’s personality, from modern sans-serifs for a sleek, professional look to classic serif fonts for a more editorial feel.

This way, you can maintain consistent branding and you make sure your posts stand out in social feeds.

The selected font will automatically apply to your image titles, keeping the layout balanced and visually appealing.
